One of my favourite things about the prequel is that we see a side of the Capitol before the Games became what they were. Katniss herself never hated her prep team despite their role in the games because she came to see they were like mindless children and (whether or not I agree with her thoughts) I always liked the acknowledgement that we are often products of our enviroment.
And Songbirds and Snakes helps prove that even more. Because there was a time, when the games weren't the big popular event that they eventually became, when even members of the Capitol were openly appalled by them:
Highbottom was horrified his ridiculously school assignment had become a real thing. Students at the academy showed genuine dislike for the games and turned away with true saddness when some of the tributes died. Not just because they lost the game but because their life was lost. It wasn't whispered for fear of treason accusations but a subject they spoke about openly with one another.
But as the games grew and became a bigger part of their culture, the Capitol was forced to treat the tributes and Districts as lesser beings that it didn't matter when they were murdered for entertainment. As such, the children learned all about this at a young age. And it grew and grew until the Capitol citizens were so brainwashed by their own leaders, they genuinely didn't see a problem with it. It wasn't even about remembering the war in the end, but rather having a bit of fun without caring at who's expense! Yes, a few people retained their horror at the games and some even went on to become rebels but for the most part, they daren't speak their doubts out loud because then they would at best be outcasts and at worst be enemies sent to trial.
I just really like the commentary about how the way we grow can affect our thoughts, beliefs and even our morality. I've always found it quite a fascinating discussion and love seeing it addressed properly.
